You may experience this when trying to use <code>exports</code> for task registration <em>and</em> composing tasks by string. In this situation, use named functions instead of string references.</p><p>During migration, you may need the <a href="https://github.com/gulpjs/undertaker-forward-reference">forward reference registry</a>.
